• VR relies on a three-dimensional, stereoscopic head-tracker displays, hand/body tracking and binaural sound. VR is an immersive, multi-sensory experience. • Computer replications that use 3D graphics and devices such as the Data Glove allows the user to interact with the virtual reality. • Virtual reality refers to interactive, multi-sensory, and viewer-centered, three dimensional computer engendered environments and the combination of technologies that are required to build these virtual environments. Virtual Reality - Evidence for the Theory In the last years, the progress made in computer science technology has brought faster and faster computers to the market.
In spite of the indifference, Virtual Reality has awoken the world in giant ways. Society should not stay doubtful of the countless possibilities it has to bring in an optimistic and technological way. Recently, in order to describe something that holds spirit and effect without having form, but having an effect on the actual, the word ‘virtual’ was used. Virtual reality is developing all the time and has found hitches not formerly considered. Applications of Virtual reality are starting to find their way into normal society.
Virtual reality (VR) can be defined as softwares that are used in the field of computer technology to create realistic environment through images, sounds and other sensations that actually reproduce the real environment. They create an imaginary setting helps the user to feel his physical presence in this environment. Through virtual reality the user can interact with the space and the objects depicted in the setting using specialized display screens, projectors, etc. It is more of a realistic simulation of a 3D environment using software and hardware that can be controlled by the human body. Virtual reality can be achieved by using a range of systems starting from headsets, omni-directional treadmills to special gloves, etc.
Virtual Reality is the buzz around these days. A very common question these days is "What is Virtual Reality?" Virtual Reality also known as VR is a three-dimensional computer generated environment experience in which the user can interact with the surroundings. This interaction is known as "telepresence" and it is this interaction that makes it unique. In other words, it is an environment created with special electronic equipment, which a user feels he is a part of without actually being there.
The definition of ‘virtual’ is near and reality is what we experience as human beings. So the term ‘virtual reality’ basically means ‘near-reality’. 2 .1 In technical terms… Technically Virtual reality is the term used to describe a three-dimensional, computer generated environment which can be examined and interacted with by a person. That person becomes part of this virtual world or is deeply involved with this environment and at the same time, is able to manipulate objects or perform a series of actions. 2.2 What’s the difference Between Virtual Reality and Augmented Reality?
It reduces the risk of real-world failures and possible injuries. (eg: Fields like law enforcement, medicine, aviation, architecture and the service) • People who can’t experience the real world such as those with disabilities can experience a virtual world as an alternative. • Travelers can be given detailed information or a virtual tour of their desired destinations with the help of virtual reality to aid them. • Virtual reality makes experiencing things that are impossible in real life such as fighting zombies in a game or flying. Cons of VR • Virtual reality being costly, not everyone who can afford it would be able to experience it.
INTRODUCTION Virtual Reality is three-dimensional environment projection, generated by a computer, which a person using special technology can explore and interact with. Person who connects to that virtual place becomes part of this created world, where she is able to perform actions and manipulate objects. Figure number 1 shows the person using virtual reality gear. Man on the picture wears head-mounted display,
Uses/Applications of VR - Advantages of VR Wherever that is too dangerous, expensive or impractical to do something, in reality, VR is the answer. From trainee fighter pilots to medical applications trainee surgeons, virtual reality allows us to take virtual risks in order to gain real-world experience. 4.1. Gaming When people think of Virtual reality, the first thing that comes to their mind would be gaming and it has become very popular in the recent years amongst teenagers. VR allows the players to be more involved in the game as compared to the traditional gaming platform, it also highlights the emotional experience to an extent as VR makes the player feel as if their actions are responsible for a particular outcome.
The first problems encountered by the researcher and related to the virtual reality are the confusion between the concepts in the term of electronic, and virtual, simulation and virtual reality, mixed reality, and the other thing is the physical and physiological problems that affect the individual when exposed to the virtual reality. There are physiological problems such as foggy vision, changes in the heart and blood vessels, change in motor performance, change in cognitive control, eye strain, stomach pain, depression, hallucinations, visual disturbances, autism, disorders of the digestive system, disorientation, unsteadiness, disorder in the machine respiratory, stress, addiction(Nichols & Patel, 2002, pp.
Augmented Reality and Virtual Reality do not use screens. There is thus no need for mobile, laptops, desktops or TV screens. In this world with Augmented Reality and Virtual Reality technolo- gy, all digital content can now be served virtually as 3D rendering or a hologram. This can place digital objects anywhere in the environment of the user. It is important that UX/UI designers care about AR/VR because the market are about to make a next move towards the post-screen world of AR/VR.
